This locking mechanism is typically in place to ensure data integrity and prevent concurrent modifications that could lead to inconsistencies.
  Causes:
  
  Concurrent Access: Another user or process is currently accessing or modifying the material, leading to a lock.

  Release Locks: If you have the necessary authorizations, you can manually delete the lock entries in SM12. However, this should be done with caution, as it may lead to data inconsistencies if the other process is still active.
  Check Background Jobs: Use transaction SM37 to check for any background jobs that might be processing the material. If you find a job that is taking too long, you may need to investigate further.
  Consult with IT Support: If the issue persists and you cannot identify the cause, it may be necessary to consult with your IT support team or SAP Basis team for further investigation.
